Dormer Pramet A940 5.30 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 5.30 mm HSS-E High Perf Multi-App Straight Shank Long Series Drill DIN/ANSI is built for reliability, versatility, and precision in everyday machining. This single, multi‑purpose drill handles a broad range of materials and applications without needing multiple tooling setups, making it a smart choice for busy workshops and tool rooms.

Engineered for precise, effortless drilling

• 130-degree point for self-centering and reduced push force, which means faster start-up and cleaner holes with less operator fatigue.
• Bright finish minimizes sticking of workpiece material to the cutting edge, promoting smoother entry and longer edge life.
• Parabolic flute design enables deeper holes in a single pass, reducing cycle time and improving hole quality in through‑holes and blind holes alike.
• Premium HSS-E material delivers higher toughness and wear resistance, making it suitable for drilling steel, aluminum, and stainless steel with dependable results.
• High performance with h10 tolerance supports accurate hole diameters even at elevated speeds and feeds, helping you meet tight tolerance requirements consistently.

Why this drill stands out

Unlike generic multi‑purpose drills, the A940 combines a tightly engineered point geometry, a high‑efficiency flute profile, and material science optimized for demanding workpieces. The result is holes that start true, stay straight, and finish with a clean edge—reducing secondary operations and scrap. The straight shank and DIN/ANSI compatibility ensure quick, secure tool changes and reliable seating in standard chucks and collets.

Ideal use cases

• Job shops and production cells drilling mixed materials like steel, aluminum, and stainless steel without swapping tools frequently.
• Through‑hole and blind-hole applications where depth and hole quality are critical.
• Projects requiring tight dimensional control with efficient cycle times thanks to deep-hole capability in a single pass.

Practical tips for best results

• Match speeds and feeds to the material being drilled, using the A940’s design to maintain stable cutting without excessive thrust.
• Use appropriate coolant or lubrication to extend edge life and minimize built‑up edge, especially on aluminum and stainless steel.
• Ensure proper workpiece clamping to maximize the centering benefits of the 130° point and to preserve hole quality over multiple holes.
